Re: [aspectj-dev] UnsupportedOperationException thrown: unable to parame

["Wes" <wes@xxxxxxxxxxxxxx>]

Compiler exceptions are definitely bugs.  

I reproduced this in HEAD and in code style (below).  

Please submit at

  http://dev.eclipse.org/bugs/enter_bug.cgi?product=AspectJ
  
Thanks for pointing this out. (Not sure if the code is correct.)
Wes

------------- Main.java
import java.util.ArrayList;
import java.util.List;

public class Main {

 public List<? extends Element> getElements() {
  return new ArrayList<Element>();
 }

 class Element {};

 static abstract aspect Base<T> {

   List<? extends T> around() : call(List<? extends T> *.*(..)) {
    return (List<? extends T>) proceed();
  }
 }

 static aspect Concrete extends Base<Element> {}

 public static void main(String[] args) {
  new Main().getElements();
 }

}
